MULTIPLE-OUTLET SILL COCK UNIT Filed Jan. 23, 1953 MiH'on Orwin AHorney2,762,387 MULTIPLE-OUTLET SILL COCK UNIT Milton Orwin, Kalamazoo, Mich.Application January 23, 1953, Serial No. 332,876 1 Claim. (Cl. 137-360)The present invention relates to the construction of sill cocks, a sillcock being a valve-controlled outlet adapted for connection to the pipeusually found in close proximity to the sill of a house to form a hoseconnection. It is often desirable to connect a series of waterconsumingunits for operation at the same time, such as a plurality of sprinklers,or a sprinkler and a waterconducting cleaning brush for scrubbing suchthings as the exterior of a house, an automobile, or sidewalk surfaces.The usual pipe carrying water from the central distributing point in thehouse to the sill cock is of such a capacity as to conduct at adequatepressure a considerable amount of flow in excess of the capacity of theusual hose. An ordinary valve unit contains several points of flowrestriction and sudden changes in flow direction, resulting in a ratherlarge pressure drop. For this reason, it is not practical to attach amultiple-outlet unit to an installed conventional single sill cock valveout let, since the resulting arrangement will cause an unduly largepressure drop and result in inadequate flow in the severalwater-conducting units.

The present invention provides a distribution chamber connected directlyto the water pipe, with suflicient area in the chamber to supply waterat adequate pressure to all parts of the chamber. The portion of thedevice opposite from the point of connection to the pipe is formed in anarcuate contour to provide room for a plurality of valve-controlledoutlets. This arcuate formation permits a rather small chamber to beutilized while still providing adequate space for manual operation ofthe valves. This feature is due to the fact that the substantiallyradial arrangement of the valves permits the inner ends of these unitsto be much closer together than the spacing requirements necessary atthe control end. The inlet to the distribution chamber is preferablytangential to the normally lowermost portion of the chamber in order topermit drainage and prevent damage from freezmg.

In addition to the spacing advantages resulting in a relatively smalldistribution chamber for a given clearance at the control ends of thevalves, the arcuate formation of the distribution chamber permitsfundamentally the same chamber to be used with a variety of valve unitarrangements. If desired, the threaded openings for receiving the outletvalves may be machined as required into standard distribution chambercastings. If it is desirable to provide thickened areas in the walls ofthe chamber surrounding these threaded openings, the present inventionwill result in the use of less molding equipment that would be necessaryif the entire unit had to be revised for each variation in thearrangement or number of valves associated with each distributionchamber.

The several features of the present invention will be analysed in detailthrough a discussion of the particular embodiments illustrated in theaccompanying drawing. In the drawing,

Figure 1 presents a plan view of a device embodying the presentinvention, with a section broken away to show the interior construction.

Figure 2 is a section taken on the plane 2-2 ure 1.

Referring to the drawing, a distribution chamber generally indicated atis preferably formed as a cast unit,

of Fignited States Patent 0 and has an intake 11 which is preferablytangent to the lowermost side 12 of the distribution chamber 10. Thethreaded opening 11 is intended to be screwed on to the end of a waterpipe, with the formed section 13 forming a pleasing configuration inconjunction with the surface of the house against which it will bepositioned on the completion of the installation.

Water entering through the inlet will proceed to fill the distributionchamber 10 and provide adequate pressure opposite the intake openings ofthe valve units 14 and 15, which are threaded into openings also shownas tangent to the lower most side 12 of the distribution chamber 10 inthe outwardly-convex surface 16 of the side of the distribution chamberopposite from the intake 11. The tangential arrangement of the inlet andoutlets facilitates complete drainage of the unit and thereby avoidsfreezing. The manual control knobs 17 and 18 for the valves 14 and 15,respectively, are spaced at a substantial distance apart, providingadequate clearance for their manual operation. In spite of this spacing,the intake ends of these valves are close enough together to permit theuse of a relatively small casting to form the distribution chamber 10.With this arrangement, the contents of the pipe to which thedistribution chamber unit is connected will be supplied to the valves 14and 15 without substantial drop in pressure, the cross-sectional area ofthe chamber 10 being sufiicient to permit the ready movement of waterwithout substantial resistance. Water-consuming units can then beconnected to the outlet openings as indicated at 19 in Figure 2, andthese units will be provided with a flow of water at a very slightreduction in pressure from that in the supply pipe.

The particular embodiments of the present invention which have beenillustrated and discussed herein are for illustrative purposes only andare not to be considered as a limitation upon the scope of the appendedclaim. In the claim, it is my intention to claim the entire inventiondisclosed herein, except as I am limited by the prior art.

I claim:

In combination with a water pipe extending horizontally through abuilding wall, a multiple outlet sill-cock unit comprising a unitaryhousing having an upper wall, a substantially plane horizontal lowerwall, a rear wall providing a vertical flange abutting said buildingwall, and an outwardly convex arcuate forward wall, said rear wallcontaining an inlet port extending through said flange and connected tosaid pipe, said port being disposed remote from said upper wall andsubstantially tangent to said lower wall, said forward wall containing aplurality of outlet ports having axes substantially normal to saidforward wall, said outlet ports being substantially tangent to saidlower wall, and in a common plane with the axis of said inlet port, anda valved fitting in each of said outlet ports, each said fitting havingan outlet at least as low as said plane and each said fitting providinga valve stem having an axis substantially normal to said forward walland radiating outwardly therefrom.
